I have a few writeups on ej 22 swaps, but most of them are more directed to phase 1 obd 1 swaps in ea82 cars. Do those writeups apply for obd 2 swaps as well or are there a few key differences? Thanks!

While either system will work, each one will have it's own strong and week points. An OBD-1 (91-94 or so EJ22) harness is a little harder to strip and setup initially but is probably more fault tolerant and less fussy overall about sensors, cats, etc.

 

The OBD-II is no doubt a better system, however it can be less forgiving to a missing fuel temp sensor, VSS problem, Upstream - Downstream O2's and possible cat codes, etc. Either one is a huge upgrade and well worth the trouble IMO.

I prefer obd1. Easy for me to tare down and label. Are you planning on stripping yours? Obd1 just requires to to eliminate the SMJ little soldering and hear shrink. But obd2 is faster and is a more efficient ecu and engine.
